Preheat the oven to 425°. In a medium bowl, toss the bread with 2 tablespoons of the olive oil. Spread the bread on a baking sheet and bake for 10 minutes, just until lightly crisp.

In the same bowl, toss the tomatoes with the olives, basil, garlic and 2 tablespoons of the olive oil. Season with salt and pepper. Add the toasted bread and cheese, toss well and transfer to a deep 10-inch glass pie plate. Drizzle the remaining 2 tablespoons of olive oil over the top and bake for 20 minutes, until the cheese is melted and the bread is browned on top. Serve hot.
